Flickering while playing videos on Chrome

I have 2 laptops from ASUS (X542UQ KabyLake + NVIDIA 940MX and X507MA GemniLake) which will have the flickering problem while playing videos in https://yandex.ru/video/search?text=%D1%84%D0%B8%D0%BB%D1%8C%D0%BC%D1%8B%20%D0%BF%D1%80%D0%BE%20%D0%BA%D0%BE%D1%81%D0%BC%D0%BE%D1%81&path=main&reqid=1513175428905465-1641906819282495832002859-man1-4483-V.
Please reference the attached file that I've recorded. It keeps showing the while macroblock and the interesting thing is it won't happen while I play the same video clips on youtube. And it won't be a problem playing with Firefox. But why I'm so sure that it's about i915 driver is due to everything good after I disable i915 while booting. It's good after I switch to NVIDIA drm on X542UQ and disable i915 on X507MA.

I also tried the kernel 4.13+ and 4.15+ but nothing changed. Then tried to build my own kernel from the current head of drm-intel-next-queued branch on git://anongit.freedesktop.org/drm-intel, the problem still remains. And maybe one thing worth mention even I don't know it causes confusion or does help. When I compiled the kernel with CONFIG_DRM_I915_ALPHA_SUPPORT=y, things would get worse. The white macroblock shows more frequently.

Any suggestions?

Comment 4 Chris Chiu 2018-01-11 14:37:57 UTC

The symptom still persists after I applied the patches you mentioned for KBL/SKL. The kernel log with drm.debug=0xe attached. Please let me know if more information required. Thanks
